Cryptocurrency Mining Post-Bitcoin

While the age of using your own computer to mine Bitcoin during spare CPU cycles has long passed, average folks aren’t entirely shut out of the cryptocurrency game yet. Luckily, Bitcoin isn’t the only game in town anymore, and with GPUs coming down Free minning in price it’s possible to build a mining rig for other currencies like Etherium.

[Chris]’s build starts with some extruded aluminum and a handful of GPUs. He wanted to build something that didn’t take up too much space in the small apartment. Once the main computer was installed, each GPU was installed upwards in the rack, with each set having its own dedicated fan. After installing a fan controller and some plexiglass the rig was up and running, although [Chris] did have to finagle the software a little bit to get all of the GPUs to work properly.

While this build did use some tools that might only be available at a makerspace, like a mill and a 3D printer, Free minning the hardware is still within reason with someone with a little cash burning a hole in their pockets. And, if Etherium keeps going up in value like it has been since the summer, it might pay for itself eventually, providing that your electric utility doesn’t charge too much for power.

And if you missed it, we just ran a feature on Etherium.  Check it out.

Ethereum: GPU Mining Is Back But For How Long?

By now, everyone and their dog has at least heard of Bitcoin. While no government will accept tax payments in Bitcoin just yet, it’s ridiculously close to being real money. We’ve even paid for pizza delivery in Bitcoin. But it’s not the only cryptocurrency in town.

Ethereum initially launched in 2015 is an open source, it has been making headway among the 900 or so Bitcoin clones and is the number two cryptocurrency in the world, with only Bitcoin beating it in value. This year alone, the Ether has risen in value by around 4000%, and at time of writing is worth $375 per coin. And while the Bitcoin world is dominated by professional, Free minning purpose-built mining rigs, there is still room in the Ethereum ecosystem for the little guy or gal.Ethereum is for Hackers

There may be many factors behind Ethereum’s popularity, however one reason is that the algorithm is designed to be resistant to ASIC mining. Unlike Bitcoin, anyone with a half decent graphics card or decent gaming rig can mine Ether, giving them the chance to make some digital currency. This is largely because mining Ethereum coins requires lots of high-speed memory, which ASICs lack. The algorithm also has built-in ASIC detection and will refuse to mine properly on them.

Small-scale Bitcoin miners were stung Free minning

when the mining technology jumped from GPU to ASICs. ASIC-based miners simply outperformed the home gamer, and individuals suddenly discovered that their rigs were not worth much since there was a stampede of people trying to sell off their high-end GPU’s all at once. Some would go on to buy or build an ASIC but the vast majority just stopped mining. They were out of the game they couldn’t compete with ASICs and be profitable since mining in its self uses huge amounts of electricity.

Economies of scale like those in Bitcoin mining tend to favor a small number of very large players, which is in tension with the distributed nature of cryptocurrencies which relies on consensus to validate transactions. It’s much easier to imagine that a small number of large players would collude to manipulate the currency, for instance. Ethereum on the other hand hopes to keep Free minning their miners GPU-based to avoid huge mining farms and give the average Joe a chance at scoring big and discovering a coin on their own computer.Ethereum Matters

Ethereum’s rise to popularity has basically undone Bitcoin’s move to ASICs, at least in the gamer and graphics card markets. Suddenly, used high-end graphics cards are worth something again. And there are effects in new equipment market. For instance, AMD cards seem to outperform other cards at the moment and they are taking advantage of this with their release of Mining specific GPU drivers for their new Vega architecture. Indeed, even though AMD bundled its hottest RX Vega 64 GPU with two games, a motherboard, and a CPU in an attempt to make the package more appealing to gamers than miners, AMD’s Radeon RX Vega 56 sold out in five minutes with Ethereum miners being blamed.

Besides creating ripples in the market for high-end gaming computers, cryptocurrencies are probably going to be relevant in the broader economy, and Ethereum is number two for now. In a world where even banks are starting to take out patents on blockchain technology in an attempt to get in on the action, cryptocurrencies aren’t as much of a fringe pursuit as they were a few years ago. Ethereum’s ASIC resistance is perhaps its killer feature, preventing centralization of control and keeping the little hacker in the mining game. Only time will tell if it’s going to be a Bitcoin contender, but it’s certainly worth keeping your eye on.

Cryptomining Syndicate Hijacks Kubernetes Clusters

Microsoft has released a new report highlighting a new series of attacks targeting a toolkit called Kubeflow which is used for running machine learning operations on top of Kubernetes clusters.

The attacks first began in April of this year and have continued with the aim of installing a cryptocurrency miner on Kubernetes clusters that are exposed to the internet and run Kubeflow.

In a blog post, security research software engineer at the Azure Security Center, Yossi Weizman provided more details on Kubeflow and why nodes used for machine learning tasks are such an attractive target for cybercriminals, saying:

“Kubeflow is an open-source project, started as a project for running TensorFlow jobs on Kubernetes. Free minning Kubeflow has grown and become a popular framework for running machine learning tasks in Kubernetes. Nodes that are used for ML tasks are often relatively powerful, and in some cases include GPUs. This fact makes Kubernetes clusters that are used for ML tasks a perfect target for crypto mining campaigns, which was the aim of this attack.”

Microsoft has tracked these attacks since they first started showing up online back in April. However, after the first attack wave, the cryptomining syndicate behind them switched from Free minning targeting general-purpose Kubernetes clusters to focus specifically on those using Kubeflow to run machine learning operations.

Based on findings from its initial investigation, the software giant now believes that misconfigured Kubeflow instances are the most likely point of entry for the attackers. This is likely the result of Kubeflow admins changing the toolkit’s default settings which exposed its admin panel Free minning online. By default, the Kubeflow management panel is only accessible from inside the Kubernetes cluster and not over the internet.

According to Weizman, a cryptomining syndicate is now actively scanning for these dashboards online. When found, the group deploys a new server image to Kubeflow clusters Free minning that runs a Monero cryptocurrency mining application called XMRig.

Server admins can check to see if their Kubeflow instances have been hacked by entering this command: kubectl get pods –all-namespaces -o jsonpath=”{.Items[*].Spec.Containers[*].Image}”  | grep -i ddsfdfsaadfs. To prevent falling victim to these attacks, server admins Free minning should make sure that Kubeflow’s daashboard is not exposed to the internet.
